E92 335i 2007 Coupe Clutch Low Bite Problem

Post by fergusond » 16 Jul 2017, 10:22

I've had my 335i (82000 miles) for over two years and its been faultless apart from the gearbox. The gearbox has always been resistive and balks if rushed, no chance of doing track days with it. The clutch pedal has always had a short lift before biting, it now seems to be too low, I reckon 2.1/2 to 3 inches. There's no slip and I've been underneath and bled the slave cylinder.

Any ideas.

thanks david

Sounds like a pressure plate problem
if the biting point gets lower it will start dragging and become difficult to select gears

My 135i certainly hasn't the slickest box - particularly 1->2 and talking to a main dealer it transpires there is a shift linkage modification officially available....at about £600!

As above, low bite suggests the clutch is on its was out.

I'm thinking of taking off that 'clutch delay device' adjacent the slave cylinder and modifying the port to a larger size. My thinking is that despite my efforts in such a confined space that its not bleeding correctly, maybe the port is blocked slightly making bleeding difficult. I'll know a bit more when I get it off.

I'll then review the clutch wear if I can get the biting point off the carpet and a bit higher. My experience with clutches is that the bite gets higher as it wears, not the other way around, but I'm always ready to be corrected if wrong.

Your correct if it was the centre plate that was wearing out
But if the pressure plate is at fault it's most likely to drag
